Congenital Heart disease

What is Congenital heart disease?


London Paediatric Cardiologist - Normal Heart

Congenital heart disease in a baby or child describes a problem with the heart's structure and function due to abnormal heart development before birth. Congenital means present at birth. This is the main area of expertise for a paediatric cardiologist (childrens heart doctor).


Normal Anatomy

The  heart  is a pump consisting of four chambers. There are  two upper collecting  chambers  and  two bottom-pumping  chambers. The left hand-side  of the heart receives oxygenated blood from the lungs and then pumps this to the body. The right-hand side of  the  body collects the  deoxygenated  (used)  blood  from  the body and then pumps this  back around  into  the lungs for  re-oxygenation.  There are one-way  valves between the upper and lower chambers of the heart and at the beginning of the major arteries to the body and lungs. There is usually   a  solid  wall of tissue  between the walls of the upper and lower chambers. The heart has its own electricity supply causing it to contract and relax (squish), thereby pumping blood to the body.
